MACHINE FOR HANDLING GRAIN.

Specification of Letters Patent.

Application filed June 16, 1908.

Patented July 12, 1910. Serial No. 438,827.

To all whom it may concern:

Be it known that we, JAMES WHITE and CHARLES COLE, both of the town ofCarberry, in the Province of Manitoba, Canada, have invented certain newand useful Improvements in Machines for Handling Grain, of which thefollowing is the specification.

Our invention relates to a labor saving machine of this class and theobject of the invention is to provide a machine which will receive awagon or such like heavy vehicle and dump it into a suitable hopper, thedumping material being elevated and directed to any desired receptacle,such elevating means being actuated by power supplied by draft animalsattached to the wagon and without unhitching them.

A further object is to provide an attachment by which material such asgrain can be withdrawn from the receptacle and elevated into a wagoncarried by the machine.

Our invention consists essentially in a main deck having suitabledetachable approaches thereto, a tiltable frame located on the main deckand provided with suitable stop blocks and wheel receiving recesses, anendless platform carried by the deck and forward of the tiltable frame ahopper located to the rear of the frame, an elevator leg located to theside of the hopper and secured to the deck, means for feeding materialfrom the hopper to the leg, means actuated by the endless platform foroperating the elevator leg, and means for returning the tiltableplatform to the normal position, the parts being arranged andconstructed as herein after more particularly described.

Figure 1 represents a side elevation of the machine, certain portionsbeing removed, and with portions of the elevator leg torn away todisclose construction. Fig. 2 is an enlarged detailed side elevation ofa brake employed to prevent the rotation of the endless platform. Fig. 3is a plan view of a machine with part of the floor removed. Fig.

4 is a detailed side elevation of a portion of the elevator leg showingthe adjustable chute connected thereto. Fig. 5 is a sectional end viewof the machine when set up for filling a wagon from a granary or car.

In the drawings like characters of refer ence indicate correspondingparts in each figure.

1 represents the main deck of a machine which is suitably supported fromthe axles 2 and 3 carrying at their ends the rear and front carnagewheels 4: and 5, respectively, 1t being understood that the axle 3 isswiveled upon a king bolt 6 in the ordinary manner.

7 and 8 are inclined platforms leading to and away from the main deck towhich they are hingedly secured at 9 thereby allowlng them to be swungbackwardly on the main deck when the machine is being moved from oneplace to another.

10 is a suitable railing appearing at each side of the deck its purposebeing to prevent restive horses from passing over the sides of the deck.The main deck is reinforced in the center on each side by the truss 11and truss rods 12.

Rearwardly of the machine is located a hopper 13 adapted to be closed byany suitable form of cover 14: the cover being level with the flooring15 of the deck when in position so that a wagon can be driven over thehopper when desired. Forwardly of the hopper the flooring is cut away at16 to admit of two similar beams 17 secured to a cross shaft 18rotatably mounted in suitable bearings formed in the supporting beams ofthe main deck. The beams are supplied forwardly with stop blocks 19 andrearwardly with recesses 20 the purpose of which will hereinafter bemore fully explained.

The parts above described constitute what is termed the tiltable frame.

21 are bearing brackets secured to the axle 2 and carrying a cross shaft22 having suitable pinions 23 mounted thereon the pinions appearing tothe inner sides of the brackets.

24: are racks secured firmly to the beams 17 and designed so as toengage with the pinions 23 throughout the motion of the tilting frame.

25 are braces passing between the beams and the racks.

26 is a chain wheel united by a chain 27 to a chain wheel 28 carried bythe shaft 29 mounted in suitable bearings secured to the main deck. 30is a further chain wheel on the shaft 29 connected through a chain 31with a chain wheel 32 keyed on the shaft 33 secured in any suitablemanner to the rail 10.

34 is a ratchet wheel located on the shaft, and 35 is a ratchet or dogplaying on the ratchet wheel.

36 is a crank having a suitable handle thereon, the crank appearing atthe inner side of the railing so as to be within con flooring of themain deck is cut away to admit of the endless platform the upper side ofwhich is slightly above the level of the remaining portion of theflooring of the deck.

42 are rollers secured to the members 39 of the platform such rollersoperating on suitable angle irons 43 located 011 the main deck. Theangle irons simply form runways for the roller and prevent the endlessplatforms saggmg between the octagonal wheels 40. 44 are rollers similarto those 42 located at the center of the platform and designed tooperate on a suitable supporting bar carried by the main deck.

The shaft 41 is extended at one side of the deck and has a pulley 45keyed to it, the pulley being connected through a cross belt 46 with asecond pulley 47 located on a shaft 48 mounted in the beams of the maindeck.

49 is an elevator leg secured to the shaft 48 by a bracket 50 and to therail 10 by bolts 51 which pass through lugs 52 carried by the leg.WVithin the leg is suitable endless conveyer 53 mounted on upper andlower wheels 53 and 54 carried upon shafts 55 and 56 respectively. Theshaft 55 is supplied with a pulley 57 which is united with the pulley 47by means of a belt 58.

59 is a chute secured to the elevator in a manner which will allow it tobe swung either way as desired. The chute has a telescoping section 60whereby it can be shortened or lengthened as desired. The hopper isprovided with a neck 13 the end of which adjoins the lower portion ofthe elevator leg when in its upright position so the material within thehopper can be fed directly to the elevator leg through the opening 49therein. Any suitable form of gate can be provided to close the neck ofthe hop per when required.

61 is a worm conveyer located within the hopper and adapted when inoperation to feed grain through the neck of the hopper and thence to theelevator leg when the gate is open. The worm is supplied at one end witha suitable coupling 62 whereby it can be detachably connected with theshaft 54 when desired. According to the construction it will be seenthat when the bolts 51 are released the leg can be swung on the shaft 48without having to disconnect the belt 58 from the pulleys. This is donewhen it is desired to move the machine from one place to another. IVhenthis is done it will be understood that the gate in the neck 13 willhave to be closed to prevent the grain in the hopper from escaping.

63 is a drum mounted upon a suitable crank shaft 63 located on the rail10.

64 is a rope or cable fastened to the drum and to the elevator legwhereby the elevator leg can be raised to its upper position by windingthe rope 011 the drum.

In order to prevent the endless platform from rotating when not desiredI have placed a friction pulley 65 on the end of the shaft 41 upon whichplays a friction bar 66 swung from the main deck by a link 67 connectedwith a bell crank 68 pivotally secured by a pin 69 to the deck. At theopposite end of the machine I have provided a hand lever 70 which ispivoted to the deck at 70 and has its lower end connected by a link 7 Owith the bell crank 68. Any suitable means is provided on the railing 10whereby the lever 70 can be held in a locked position.

In order that the device may be used for loading a wagon from a granaryor such like I have provided a worm conveyer 71 the shaft 7 2 of whichis connected to the shaft 56 by means of a universal joint at 73. Ametal sheet 74 is secured to the lower end of the elevator leg andpasses beneath the adjoining end of the conveyer 71, and the elevatorleg is supplied with an opening 75 to the side adjoining the conveyer inorder to admit grain to the leg from the conveyer.

WVhen it is required to unload a wagon filled with grain and elevate itinto a car with our machine the driver drives his team onto the maindeck passing up the sloped platform 7. The cover of the hopper is atthis time in its closed position and the tiltable frame is in itshorizontal position being held by the action of the pawl on the ratchetwheel. WVhen the wagonhas reached the position where the front wheelsare engaging the blocks 19 and the rear wheels are in the recesses 20the team is stopped being at this time on the endless platform 88. Thecover of the hopper is then removed and the ratchet 35 is released fromthe ratchet wheel. The recesses and the blocks above mentioned are solocated in respect to the shaft 18 that a wagon filled with grain isunevenly balanced on the platform the greater part of the weight beingtoward the rear. Consequently as soon as the ratchet is released thewagon tilts backwardly and the grain flows from it directly to thehopper thereby emptying the wagon. The driver next releases the frictionbar 66 from the wheel 65 by means of the lever 70 and starts his teamthe result being that the revolving platform moves and the team remainsstationary in respect to the machine. The belt connections between therevolving platform and the elevator leg are such'that the graindeposited in the hopper is withdrawn by the worm and carried by thebuckets or carriers to the top of the leg where it is directed to thechute 59 and can be deposited in any desired receptacle such as a car orgranary. As soon as the load of grain has been elevated from the hopperthe driver or teamster throws the friction bar into engagement with thewheel and stops the rotation of the platform. The team immediatelyadvances with the result that the rear wagon wheels begin to mount thebar 37, and in doing so transfers the greater part of the Weight of thewagon forwardly of the rod 18 so that the tilting frame is brought tothe horizontal position. When this movement is taking place the ratchetis escaping over the ratchet wheel and finally holds the tilting framein its horizontal position when the movement is complete. The wagon isthen driven off the main deck by way of the platform 8. When it isdesired to use the machine for loading a wagon from a granary the emptywagon is driven onto the main deck and the tiltable frame is kept in thehorizontal position the endless frame being allowed to rotate. Theconveyer 71 is attached to the machine and the gate controlling theopening 75 is opened. The extending end of the conveyer is passed intothe granary as represented at 7 7 the grain being withdrawn therefrom bythe conveyer and deposited in the elevator leg where it is elevated anddirected to the chute 59 which enters the wagon. As soon as the wagon isfilled the friction bar is thrown into engagement with the wheel 65 andthe team is driven from the main deck.

WVhat we claim as our invention is:

In a machine of the class described, the combination with the main deck,a hopper located toward the rear end thereof, an elevator leg pivoted tothe deck, a worm conveyer located in the bottom of the hopper, upper andlower cross'shafts in the elevator, an endless conveyer passing oversaid shafts, means for detachably engaging the worm conveyer to thelower shaft, and means for closing the opening between the hopper andelevator when the elevator is swung on its pivot.
